Ventilation

We get this question a lot and it is easy to understand why. These units do feature a heat exchanger similar to the technology found in HRVs but the Ultra-Aire XT units utilize the heat exchanger to pre-cool the incoming…

“Does fresh air ventilation only occur when the Ultra-Aire dehumidifier is operating? Does the dehumidifier start and stop according to a humidistat? Can ventilation be controlled separately from dehumidification?” The Ultra-Aire DEH3000 controller allows independent operation of the fresh air ventilation,…

Wintertime moisture problems use to mean overly dry air that required adding humidity. This is changing with the construction of tightly built, energy-efficient new homes and energy upgrades in older homes. These homes may experience wintertime problems caused by excessive…

Teddy Bear (a.k.a. Ken Gehring) explains why fresh air ventilation and dehumidification are the proper solutions for controlling pollutants and moisture in order to achieve a comfortable and healthy home. Need for Ventilation & Dehumidification
